Diagnose first. Then repair.
We build tools to find the real fault first, before any part gets replaced. The tests are free and made by technicians who repair boards every day. They run in your browser and nothing is uploaded.
How it works
Pick your device. Every test runs in your browser and nothing is uploaded.
Stuck? The forum has real repair cases with the readings that found the fault.
What's wrong?
Laptop error, a phone that will not charge, a drifting stick? Pick the device, then tap what you see. You land in the right guide or test. Dead device? Open this page on any other phone or computer and follow the steps from there.
What guessing does to a board
- Lifted pads and torn traces. Every chip removal takes the board to soldering temperature; pads under the chip can lift, fine traces can tear.
- Weaker layers. The fibreglass layers can blister or delaminate, especially after the board has already been heated before.
- Brittle joints. Each reflow thickens the brittle intermetallic layer inside the solder joints, so they crack sooner.
- Damaged neighbours. Chips and tiny capacitors next to it are heated too - their joints reflow and capacitors can crack from the thermal shock.
One diagnosed repair = one heat cycle on one part. A guessing repair can mean three or four.
E-waste in numbers
Keeping every smartphone in the world in use for one more year would save as much CO₂ by 2030 as taking 4.7 million cars off the road.
What the right diagnosis saves
A dead board mostly has one fault. One shorted part or one missing rail. You find it by measuring. Guessing means swapping chips until something works.
A shorted capacitor costs a few cents. Changing the charging chip or the whole board just to see costs hundreds, and most of the time it was not the fault.
Every device powers on in the same order every time. Measure where it stops and you know which stage to check, so you don't wait for parts you never needed.
When we change only the faulty part the board stays close to factory condition. The device keeps working for years and does not come back.

Free, private, built to keep devices alive
In 15 years at the bench we saw too many good devices go in the bin because nobody found the real fault. Our Hardware Specialist and Senior Repair Technicians built these tools so more devices get fixed instead of thrown away. If they helped you, a review helps the next person find them, and your support pays for the next fix.
> goal: Less e-waste · Greener Earth
We find the real fault before parts are replaced, so fewer working batteries, boards and devices end up as e-waste.
